Pleurotus nebrodensis is an edible and commercially available mushroom in Korea. This study was conducted in order to evaluate the anticancer and immunopotentiating activities of crude polysaccharides, extracted in methanol, neutral saline, and hot water (hereafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of P. nebrodensis. ${\beta}$-Glucan and protein contents in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. nebrodensis ranged from 23.79~36.63 g/100 g and 4.45~6.12 g/100 g, respectively. Crude polysaccharides were not cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at a range of $10{\sim}2,000{\mu}g/mL$. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 11.76~27.06% in mice previously inoculated with sarcoma 180. Treatment with Fr. NaCl resulted in an increase in the numbers of spleen cells by 1.49 fold at the concentration of $50{\mu}g/mL$, compared with control. Fr. HW improved the immuno-potentiating activity of B lymphocytes through an increase in alkaline phosphatase activity by 1.65 fold, compared with control at $200{\mu}g/mL$. Maximum production of nitric oxide ($14.3{\mu}M$) was recorded in the Fr. NaCl fraction at $200{\mu}g/mL$. Production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6) was significantly higher, compared to control, and IL-6 production was highest, in contrast to TNF-${\alpha}$, IL-$1{\beta}$, and positive control, concanavalin at the tested concentration of the various fractions. Results of the current study suggest that polysaccharides extracted from P. nebrodensis have a strong anticancer effect and may be useful as an ingredient of biopharmaceutical products for treatment of cancer.

To develop a natural antioxidative peptide, the gelatin was extracted from fish (Yellowfin sole) skin by hot $water(50^{\circ}C)$ extraction method and hydrolyzed with Alcalase, pronase and collagenase through a continuous 3-step membrane reactor. Each step enzymatic hydrolysates were determined the antioxidative activity and their synergistic effects, compared with $\alpha-tocopherol$ and butylated hydroxytoluene (BHT). Also, we tried to investigate the antioxidative disposition of peptide which was successfully separated by gel filtration, ion-exchange chromatography, and HPIC in cultured rat hepatocytes intoxicated with tert-butyl hydroperoxide (TBHP). Second step enzymatic hydrolysate (SSEH) among all hydrolysates and $\alpha-tocoperol$ was showed the strongest antioxidative activity. The optimum concentration of antioxidative activity for SSEH was $1\%(w/w)$ in linoleic acid. The synergistic effects were increased in using the hydrolysate with tocopherol and BHT. In the presence of the peptide isolated from SSEH, supplemented hepatocytes exposed to TBHP showed that delayed cell killing and decreased significantly the lipid peroxidation, compared with hepatocytes not cultured with isolated peptide.
As one of the chemical and experimental study on cancer treatment in Korea oriental medicine, we investigated the clinical characteristics on the treatment of cancer patients in oriental medical hospital. Furthermore, we carried out the cytotoxicity test of extracts of herbal medicine. The results are as follows: About Clinical Aspects of the Orient낄 Medical Cancer Treatment- (1) Clinical experience is that 420 Oriental medical hospitals were surveyed. Number of cancer patiens treated by one oriental medical doctor was under 10(about 60%)or from 10 to 20(about 30%). (2) Diagnostic Procedure Is that more than 80% of cancer patients were diagnosed by medical doctor of western hospital. (3) Therapeutic Method is that combination of oriental and western medical treatment was used in oriental medical hospital. (4) Relationship between cancer and constitutions is that to the relationship between cancer and constitutions, about 75% responded and most were considered to be Um. About Experimental Study- Toevaluate the direct cytotoxicity of hot water and methanol extracts of 34 oriental medical prescriptions on stomach cancer cell, SRB assay was carried out. (1) The $IC_{50}$ value of water extract of Samsoum was $19{\mu}g/ml$ and that of methanol extract was $15{\mu}g/ml$ so that we confirmed Samsoum has a strong direct cytotoxicity. (2) The $IC_{50}$ values of water extract of Coptidis Rhizoma, methanol extract of Caesalpiniae Lignum and Draba Semen were $10{\mu}g/ml$, $9{\mu}g/ml$ and $12.5{\mu}g/ml$ respectively, so that we confirmed Coptidis Rhizoma, Caesalpiniae Lignum and Drabs Semen have a strong direct cytototoxicity.

Background & Objectives: Gastric cancer is a leading cause of cancer-related deaths in both sexes in Iran. This study was designed to assess upper GI endoscopic findings among people > 50 years targeted in a mass screening program in a hot-point region. Methods: Based on the pilot results in Guilan Cancer Registry study (GCRS), one of the high point regions for GC-Lashtenesha- was selected. The target population was called mainly using two methods: in rural regions, by house-house direct referral and in urban areas using public media. Upper GI endoscopy was performed by trained endoscopists. All participants underwent biopsies for rapid urea test (RUT) from the antrum and also further biopsies from five defined points of stomach for detection of precancerous lesions. In cases of visible gross lesions, more diagnostic biopsies were taken and submitted for histopathologic evaluation. Results: Of 1,394 initial participants, finally 1,382 persons (702 women, 680 men) with a mean age of $61.7{\pm}9.0$ years (range: 50-87 years) underwent upper GI endoscopy. H. pylori infection based on the RUT was positive in 66.6%. Gastric adenocarcinoma and squamous cell carcinoma of esophagus were detected in seven (0.5%) and one (0.07%) persons, respectively. A remarkable proportion of studied participants were found to have esophageal hiatal hernia (38.4%). Asymptomatic gastric masses found in 1.1% (15) of cases which were mostly located in antrum (33.3%), cardia (20.0%) and prepyloric area (20.0%). Gastric and duodenal ulcers were found in 5.9% (82) and 6.9% (96) of the screened population. Conclusion: Upper endoscopy screening is an effective technique for early detection of GC especially in high risk populations. Further studies are required to evaluate cost effectiveness, cost benefit and mortality and morbidity of this method among high and moderate risk population before recommending this method for the GC surveillance program at the national level.

We checked the presence of phospholipase $A_2(PLA)_2$ which could split the ester bond at the position 2 in the glycerol backbone of glycerophospholipids, in the cells of hyperthermophiles of Pyrococcus horikoshii and Sulfolobus acidocaldarius. The results obtained are as follows; (1). Pyrococcus horikoshii cells were grown in obligate anaerobic conditions at $95^{\circ}C$ and they needed sulfur as energy source instead of oxygen, while Sulfolobus acidocaldarius species grew well in the aerobic medium (pH 2.5) containing yeast and sucrose at $75^{\circ}C$. (2). Pyrococcus horikoshii cells produced phospholipase $A_2$ in the cell culture media although this species did not show lipase activity at least in the pH range of 1.5 ${\sim}$ 3.5. Sulfolobus acidocaldarius cells produced lipase hydrolyzing triacylglycerols such as triolein, but did not split any kind of phospholipids used as substates. (3). The compound of 1-decanoyl-2-(p-nitrophenylglutaryl) phosphatidylcholine was not suitable for a substrate in this experiment, though frequently used as a subtrate for checking presence of phospholipase $A_2$, for its decomposi-tion in this experiment. The L-${\alpha}$-phosphatidylcholine-${\beta}$-[N-7-nitrobenz-2-oxa-1, 3-diazol]aminohexanoyl-${\gamma}$-hexadecanoyl labelled with a fluorescent material, did not show any migration of acyl chains in the molecule during the reaction with phospholipase $A_2$ under a hot condition. (4). Phospholipase $A_2$ in the cells of Pyrococcus horikoshii, showed the optimum activity at $pH6.7{\sim}7.2$ and $95{\sim}105^{\circ}C$, respectively, and was activated by addition of calcium chloride solution. Andthe phospholipase $A_2$ specifically hydrolyzed glycero-phospholipids such as phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl serine and phosphatidyl inositol, but could not split phospholipid containing ether bonds in the molecule such as DL -${\alpha}$-phosphatidylcholine-${\beta}$-palmitoyl-${\gamma}$-O-hexadecyl, DL-${\alpha}$-phosphati- dylcholine-${\beta}$- oleoyl-${\gamma}$-O-hexadecyl, DL-phosphatidylcholine-dihexadecyl.

Effect of food additives on the heat sensitivity of listeria monocytogenes H-12 inoculated into Pollack surimi was investigated and also confirmed the effectiveness of various decontamination method such as tap water washing, chlorination, ultraviolet irradiation and heat treatment haying been applied on cooking utensils. Food additives such as polyphosphate, chitosan, and potassium sorbate increased heat sensitivity of t monocytogenes H-12 and polyphosphate showed the strongest synergistic effect. The tested strain was not detected from stainless steel and plastic cutting board contaminated with $10^4{\~}10^5/cm^2$ of L monocytogenes H-12 after tap water washing for 10 seconds or 1 minute, but washing effect was not found in wooden cutting board. The chlorination of stainless steel and plastic cutting board for 10 seconds with $5{\~}50 ppm$ solution eliminated all cells of the contaminated strain, however any change of the viable cell count was not observed in the chlorination of wooden cutting board, W irradiation on stainless steel and plastic cutting board for 5 minutes with 15 W above 30 cm eliminated the contaminated strain, but the tested strain was still found after 60 seconds of irradiation on wooden cutting board. The treatment of hot water on all used cutting boards for 10 seconds at $70^{\circ}C$ resulted in complete loss of viability of the contaminated strain.

In this study, the immunomodulatory activities of crude polysaccharides from makgeolli were investigated. Crude polysaccahrides from makgeolli (RWW) were isolated by hot water extraction ($100^{\circ}C$, 30 min), ethanol precipitation (four volumes of 95% ethanol), dialysis (MWCO: 6,000~8,000), and lyophilization. The major constituents in RWW were neutral sugar (87.3%), uronic acid (2.5%), and protein (10.2%). RWW showed potent anti-complementary activity as well as increased cell proliferation of RAW 264.7 macrophages. The immunomodulatory effects of RWW were also analyzed based on cytokine production of macrophages. Macrophages stimulated with RWW produced cytokines such as interleukin (IL)-6, IL-12, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. These data indicate that RWW may have immunomodulatory effects through activation of the complement system and macrophages, which are a part of natural immunity.

This study was initiated in order to investigate the anticancer and immunomodulating activities of crude polysaccharides extracted in methanol, neutral saline, and hot water (hereinafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of Panellus serotinus. Content of ${\beta}$-glucan and protein in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. serotinus ranged from 22.92~28.52 g/100 g and 3.24~3.68 g/100 g, respectively. In vitro cytotoxicity tests, none of the various fractions of crude polysaccharides were cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at the tested concentration. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 23.53~44.71% in mice previously inoculated with sarcoma 180. Treatment with Fr. HW resulted in an increase in the numbers of spleen cells by 1.3 fold at the concentration of $50{\mu}g/mL$ compared with control. Treatment with Fr. NaCl resulted in improvement of the immuno-potentiating activity of B lymphocytes by increasing the alkaline phosphatase activity by 1.4 fold, compared with control, at the concentration of $200{\mu}g/mL$. Among the three fractions, maximum nitric oxide ($13.48{\mu}M$) was recorded at $500{\mu}g/mL$ in Fr. HW. Production of tumor necrosis factor alpha, interleukin-$1{\beta}$, and interleukin-6 was significantly higher, compared to the positive control, concanavalin A, at the tested concentration. Therefore, treatment with crude polysaccharides extracted from the fruiting body of P. serotinus could result in improvement of antitumor activity.

This study was indicated to enhance the anti-inflammation activities by the fermentation of the fruits of Aronia melanocarpa (Michx.) Elliott. The extracts by 70% ethanol (EE) showed better biological activities than those by hot water (WE) from campared result of the effect of extraction solvents. Then, the extract from 70% ethanol extraction was further fermented by lactic acid, denoted as FEE. For antioxidant activities, the FEE had showed the highest value as 0.832 of reducing powder, in comparison with those of EE and WE. Cytotoxicity of the water extraction (WE) was measured for 12.06% in addition of $1.0mg/m{\ell}$ of FEE. For anti-inflammation activities, NO production from the macrophage, RAW 264.7 was observed as $7.24{\mu}M$ and $8.52{\mu}M$ from FEE and EE, respectively. Prostaglandin $E_2$ ($PGE_2$) production from human fibroblast cell, CCD-986sk, was also estimated for $152pg/m{\ell}$ in addition of $1.0mg/m{\ell}$ of the FEE. The lowest production of both IL-6 and TNF-${\alpha}$ were $3.5pg/m{\ell}$ and $865.5pg/m{\ell}$, respectively in addition of $1.0mg/m{\ell}$ of the FEE, whereas $74.5pg/m{\ell}$ and $982.4pg/m{\ell}$ in treated with same concenrations of the EE. It was also found that the FEE was higher amounts than other extracts through HPLC analysis of the anthocyanins. These results strongly indicate that fermentation process of the lactic acid could enhance anti-inflammation activities of extracts by increasing the amounts of the anthocyanins, especially cyanidin-galactoside. Our results suggest that the application of the fermentation process for other medicinal herbs can be improved their biological activities.
